DETAILED DESCRIPTION
[0024] Refer to the attached Figures 2 to 6From the structure shown, it can be understood that an exemplary operation process of cleaning itself of the present application is:
[0025] A ball valve includes a ball core 01, a passage 02 is provided in the middle of the ball core 01, a concave platform 04 is formed on the rear side of the passage 02, an inner ring 05 is detachably connected to the concave platform 04, a rotating shaft 06 is rotatably connected to the middle of the inner ring 05, the axis of the rotating shaft 06 coincides with the axis of the passage 02, a plurality of spiral pieces 07 are distributed on the rotating shaft 06 along the axis of the rotating shaft 06, and the outer edges of the spiral pieces 07 are in contact with the inner wall of the passage 02; when the fluid passes through the passage 02, the fluid is moved from the back to the front. When the fluid passes through the spiral piece 07, it can push the spiral piece 07, so that the spiral piece 07 rotates under the restriction of the rotating shaft 06, thereby making multiple spiral pieces 07 rotate along the axis of the rotating shaft 06, and the outer edge of the spiral piece 07 can be used to make friction contact with the inner wall of the aisle 02, so as to scrape off the sticky impurities on the inner wall of the aisle 02 and take them away with the fluid, thereby preventing the impurities from sticking to the inner wall of the aisle 02 and affecting the passage of the fluid, thereby preventing the aisle 02 from being blocked.
[0026] Refer to the attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of the rapid assembly of the present application is:
[0027] The ball valve also includes two valve shells 14 that can be interlocked and connected together. A spherical wall 16 is formed on the inner side of the valve shell 14. The ball core 01 contacts between the two spherical walls 16. An outlet 21 is formed on the outer end of the front valve shell 14, and an inlet 20 is formed on the outer end of the rear valve shell 14. The two valve shells 14 can be quickly connected by bolts, which can facilitate operation when the ball valve is assembled. At the same time, the outer wall surface of the ball core 01 contacts the two spherical walls 16 to improve the sealing performance.
[0028] Refer to the attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of the present application is as follows:
[0029] The upper side of the valve housing 14 is formed with a groove 15, and the upper sleeve 13 is detachably connected to the two grooves 15, and the upper tube 09 is rotatably connected to the upper sleeve 13. The upper end of the upper tube 09 is fixedly connected to the turning handle 10, and the upper tube 09 is fixedly connected to the ball core 01; by holding the turning handle 10 by hand, the upper tube 09 can be driven to rotate, so that the upper tube 09 drives the ball core 01 to rotate in the horizontal direction in the two valve housings 14, and the front and rear ends of the aisle 02 can be aligned with the outlet 21 and the inlet 20 respectively, so that the fluid can flow.
[0030] Refer to the attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of the present application for facilitating unblocking is:
[0031] A semicircular groove 17 is provided on the lower side of the valve housing 14, and a lower tube 08 is formed at the lower end of the ball core 01. The lower tube 08 is rotatably connected in the two semicircular grooves 17. The ball core 01, the lower tube 08 and the upper tube 09 are located on the same axis. The interior of the ball core 01 is empty and connected to the lower tube 08 and the upper tube 09. A plug 24 is buckled in the lower tube 08. When the temperature is low and the ball core 01 remains closed, the remaining fluid in the passage 02 is easily frozen, resulting in blockage inside the passage 02. At this time, hot water can be passed into the ball core 01 through the upper tube 09 and flow out from the lower tube 08, so that the hot water increases the temperature of the ball core 01, and the temperature of the remaining fluid in the passage 02 is increased to thaw, thereby achieving dredging of the passage 02.
[0032] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of discharging fluid of the present application is:
[0033] The front and rear ends of the valve housing 14 are both formed with lateral semicircular holes 19, the inner walls of the lateral semicircular holes 19 are provided with threads, and the two lateral semicircular holes 19 on the same side of the front and rear are connected with side plugs 25; when closing the ball valve, the ball core 01 is rotated to align the two ends of the aisle 02 with the lateral semicircular holes 19 on the front and rear sides respectively, at which time the outer wall of the ball core 01 blocks the outlet 21 and the inlet 20 to close them, and the fluid remaining in the aisle 02 can flow outward when the side plug 25 is removed, thereby allowing the fluid to be discharged from the aisle 02 to avoid corrosion of the inner wall of the aisle 02 due to long-term residue.
[0034] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process guided by the present application is:
[0035] It also includes two branch pipes 26, which can be connected to the inside of the lateral semicircular holes 19 on the same side of the front and rear sides respectively, and the pipeline can be connected to the outer end of the branch pipe 26 to guide the fluid limit cover in the passage 02 out;
[0036] In addition, a side opening 03 is provided on the side of the ball core 01, and the side opening 03 and the passage 02 are perpendicular to each other in the horizontal plane. When the ball core 01 is rotated to align the side opening 03 with the inlet 20, the two ends of the passage 02 are respectively aligned with the two branch pipes 26. At this time, the fluid can be discharged outward from the left and right sides of the ball valve, and the flow of the fluid to the outlet can be increased, thereby diverting the fluid flowing out of the ball valve.
[0037] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of avoiding rotation of the present application is:
[0038] The upper tube 09 is fixedly connected with an upper plate 11, and the upper end surface of the upper plate 11 is provided with a mark for indicating the rotation position of the upper tube 09; the mark can be used to understand the rotation position of the ball core 01 driven by the upper tube 09, and understand the state of the ball valve being open, diverted or closed;
[0039] Three locking holes 12 are provided on the outer wall of the upper plate 11, and the angle between every two adjacent locking holes 12 in the horizontal direction is ninety degrees. A side plate 22 is formed on the valve shell 14 on the rear side, and a locking shaft 23 is slidably connected to the upper end of the side plate 22. A spring is fixedly connected between the locking shaft 23 and the side plate 22, and the locking shaft 23 can extend into the locking hole 12; when the ball core 01 is rotated, the locking shaft 23 can be pulled outward to squeeze the spring, and after rotation, one of the locking holes 12 can be aligned with the locking shaft 23, and then the locking shaft 23 is released. Under the action of the spring, the locking shaft 23 extends into the locking hole 12, thereby limiting the upper plate 11 and preventing the upper plate 11 from rotating accidentally, thereby preventing the upper tube 09 from driving the ball core 01 to rotate accidentally, and the state of the ball core 01 can be maintained.
[0040] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of limiting the fluid of the present application is:
[0041] A plurality of combing plates 18 are fixedly connected to the inner wall of the inlet 20. When the fluid flows through the inlet 20, it can be restricted by the plurality of combing plates 18 to prevent the fluid from swirling, so that the fluid can flow straight from right back to front, ensuring that the force of the fluid on the spiral sheet 07 can drive the spiral sheet 07 to rotate.
